		<h1>GNU GENERAL PUBLIC LICENSE</h1>
		<h2>Version 2, June 1991</h2>
		
		<p>Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51
			Franklin St, Fifth Floor, Boston, MA 02110-1301 USA</p>
		<p>Everyone is permitted to copy and distribute verbatim copies of
			this license document, but changing it is not allowed.</p>
		
		<h2>Preamble</h2>
		
		<p>The licenses for most software are designed to take away your
			freedom to share and change it. By contrast, the GNU General
			Public License is intended to guarantee your freedom to share
			and change free software--to make sure the software is free for
			all its users. This General Public License applies to most of
			the Free Software Foundation's software and to any other
			program whose authors commit to using it. (Some other Free
			Software Foundation software is covered by the GNU Library
			General Public License instead.) You can apply it to your
			programs, too.</p>
		
		<p>When we speak of free software, we are referring to freedom, not
			price. Our General Public Licenses are designed to make sure
			that you have the freedom to distribute copies of free software
			(and charge for this service if you wish), that you receive
			source code or can get it if you want it, that you can change the
			software or use pieces of it in new free programs; and that you
			know you can do these things.</p>
		
		<p>To protect your rights, we need to make restrictions that forbid
			anyone to deny you these rights or to ask you to surrender the
			rights. These restrictions translate to certain
			responsibilities for you if you distribute copies of the
			software, or if you modify it.</p>
		
		<p>For example, if you distribute copies of such a program, whether
			gratis or for a fee, you must give the recipients all the rights
			that you have. You must make sure that they, too, receive or can
			get the source code. And you must show them these terms so they
			know their rights.</p>
		
		<p>We protect your rights with two steps: (1) copyright the
			software, and (2) offer you this license which gives you legal
			permission to copy, distribute and/or modify the
			software.</p>
		
		<p>Also, for each author's protection and ours, we want to make
			certain that everyone understands that there is no warranty
			for this free software. If the software is modified by someone
			else and passed on, we want its recipients to know that what they
			have is not the original, so that any problems introduced by
			others will not reflect on the original authors'
			reputations.</p>
		
		<p>Finally, any free program is threatened constantly by software
			patents. We wish to avoid the danger that redistributors of a
			free program will individually obtain patent licenses, in
			effect making the program proprietary. To prevent this, we
			have made it clear that any patent must be licensed for
			everyone's free use or not licensed at all.</p>
		
		<p>The precise terms and conditions for copying, distribution and
			modification follow.</p>
		
		<h2>GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING,
			DISTRIBUTION AND MODIFICATION</h2>
		
		<p>0. This License applies to any program or other work which
			contains a notice placed by the copyright holder saying it may
			be distributed under the terms of this General Public License.
			The "Program", below, refers to any such program or work, and a
			"work based on the Program" means either the Program or any
			derivative work under copyright law: that is to say, a work
			containing the Program or a portion of it, either verbatim or
			with modifications and/or translated into another language.
			(Hereinafter, translation is included without limitation in
			the term "modification".) Each licensee is addressed as
			"you".</p>
		
		<p>Activities other than copying, distribution and modification
			are not covered by this License; they are outside its scope. The
			act of running the Program is not restricted, and the output
			from the Program is covered only if its contents constitute a
			work based on the Program (independent of having been made by
			running the Program). Whether that is true depends on what the
			Program does.</p>
		
		<p>1. You may copy and distribute verbatim copies of the Program's
			source code as you receive it, in any medium, provided that you
			conspicuously and appropriately publish on each copy an
			appropriate copyright notice and disclaimer of warranty;
			keep intact all the notices that refer to this License and to the
			absence of any warranty; and give any other recipients of the
			Program a copy of this License along with the Program.</p>
		
		<p>You may charge a fee for the physical act of transferring a copy,
			and you may at your option offer warranty protection in
			exchange for a fee.</p>
		
		<p>2. You may modify your copy or copies of the Program or any portion
			of it, thus forming a work based on the Program, and copy and
			distribute such modifications or work under the terms of
			Section 1 above, provided that you also meet all of these
			conditions:</p>
		
		<p>a) You must cause the modified files to carry prominent notices
			stating that you changed the files and the date of any
			change.</p>
		
		<p>b) You must cause any work that you distribute or publish, that in
			whole or in part contains or is derived from the Program or any
			part thereof, to be licensed as a whole at no charge to all third
			parties under the terms of this License.</p>
		
		<p>c) If the modified program normally reads commands
			interactively when run, you must cause it, when started
			running for such interactive use in the most ordinary way, to
			print or display an announcement including an appropriate
			copyright notice and a notice that there is no warranty (or
			else, saying that you provide a warranty) and that users may
			redistribute the program under these conditions, and telling
			the user how to view a copy of this License. (Exception: if the
			Program itself is interactive but does not normally print such
			an announcement, your work based on the Program is not required
			to print an announcement.)</p>
		
		<p>These requirements apply to the modified work as a whole. If
			identifiable sections of that work are not derived from the
			Program, and can be reasonably considered independent and
			separate works in themselves, then this License, and its
			terms, do not apply to those sections when you distribute them
			as separate works. But when you distribute the same sections as
			part of a whole which is a work based on the Program, the
			distribution of the whole must be on the terms of this License,
			whose permissions for other licensees extend to the entire
			whole, and thus to each and every part regardless of who wrote
			it.</p>
		
		<p>Thus, it is not the intent of this section to claim rights or
			contest your rights to work written entirely by you; rather,
			the intent is to exercise the right to control the distribution
			of derivative or collective works based on the Program.</p>
		
		<p>In addition, mere aggregation of another work not based on the
			Program with the Program (or with a work based on the Program) on
			a volume of a storage or distribution medium does not bring the
			other work under the scope of this License.</p>
		
		<p>3. You may copy and distribute the Program (or a work based on it,
			under Section 2) in object code or executable form under the
			terms of Sections 1 and 2 above provided that you also do one of
			the following:</p>
		
		<p>a) Accompany it with the complete corresponding
			machine-readable source code, which must be distributed
			under the terms of Sections 1 and 2 above on a medium customarily
			used for software interchange; or,</p>
		
		<p>b) Accompany it with a written offer, valid for at least three
			years, to give any third party, for a charge no more than your
			cost of physically performing source distribution, a
			complete machine-readable copy of the corresponding source
			code, to be distributed under the terms of Sections 1 and 2 above
			on a medium customarily used for software interchange;
			or,</p>
		
		<p>c) Accompany it with the information you received as to the offer
			to distribute corresponding source code. (This alternative
			is allowed only for noncommercial distribution and only if you
			received the program in object code or executable form with
			such an offer, in accord with Subsection b above.)</p>
		
		<p>The source code for a work means the preferred form of the work for
			making modifications to it. For an executable work, complete
			source code means all the source code for all modules it
			contains, plus any associated interface definition files,
			plus the scripts used to control compilation and installation
			of the executable. However, as a special exception, the source
			code distributed need not include anything that is normally
			distributed (in either source or binary form) with the major
			components (compiler, kernel, and so on) of the operating
			system on which the executable runs, unless that component
			itself accompanies the executable.</p>
		
		<p>If distribution of executable or object code is made by offering
			access to copy from a designated place, then offering
			equivalent access to copy the source code from the same place
			counts as distribution of the source code, even though third
			parties are not compelled to copy the source along with the
			object code.</p>
		
		<p>4. You may not copy, modify, sublicense, or distribute the
			Program except as expressly provided under this License. Any
			attempt otherwise to copy, modify, sublicense or distribute
			the Program is void, and will automatically terminate your
			rights under this License. However, parties who have received
			copies, or rights, from you under this License will not have
			their licenses terminated so long as such parties remain in
			full compliance.</p>
		
		<p>5. You are not required to accept this License, since you have not
			signed it. However, nothing else grants you permission to
			modify or distribute the Program or its derivative works.
			These actions are prohibited by law if you do not accept this
			License. Therefore, by modifying or distributing the Program
			(or any work based on the Program), you indicate your
			acceptance of this License to do so, and all its terms and
			conditions for copying, distributing or modifying the
			Program or works based on it.</p>
		
		<p>6. Each time you redistribute the Program (or any work based on
			the Program), the recipient automatically receives a license
			from the original licensor to copy, distribute or modify the
			Program subject to these terms and conditions. You may not
			impose any further restrictions on the recipients' exercise
			of the rights granted herein. You are not responsible for
			enforcing compliance by third parties to this License.</p>
		
		<p>7. If, as a consequence of a court judgment or allegation of
			patent infringement or for any other reason (not limited to
			patent issues), conditions are imposed on you (whether by
			court order, agreement or otherwise) that contradict the
			conditions of this License, they do not excuse you from the
			conditions of this License. If you cannot distribute so as to
			satisfy simultaneously your obligations under this License
			and any other pertinent obligations, then as a consequence you
			may not distribute the Program at all. For example, if a patent
			license would not permit royalty-free redistribution of the
			Program by all those who receive copies directly or indirectly
			through you, then the only way you could satisfy both it and this
			License would be to refrain entirely from distribution of the
			Program.</p>
		
		<p>If any portion of this section is held invalid or unenforceable
			under any particular circumstance, the balance of the section
			is intended to apply and the section as a whole is intended to
			apply in other circumstances.</p>
		
		<p>It is not the purpose of this section to induce you to infringe any
			patents or other property right claims or to contest validity
			of any such claims; this section has the sole purpose of
			protecting the integrity of the free software distribution
			system, which is implemented by public license practices.
			Many people have made generous contributions to the wide range
			of software distributed through that system in reliance on
			consistent application of that system; it is up to the
			author/donor to decide if he or she is willing to distribute
			software through any other system and a licensee cannot impose
			that choice.</p>
		
		<p>This section is intended to make thoroughly clear what is
			believed to be a consequence of the rest of this License.</p>
		
		<p>8. If the distribution and/or use of the Program is restricted in
			certain countries either by patents or by copyrighted
			interfaces, the original copyright holder who places the
			Program under this License may add an explicit geographical
			distribution limitation excluding those countries, so that
			distribution is permitted only in or among countries not thus
			excluded. In such case, this License incorporates the
			limitation as if written in the body of this License.</p>
		
		<p>9. The Free Software Foundation may publish revised and/or new
			versions of the General Public License from time to time. Such
			new versions will be similar in spirit to the present version,
			but may differ in detail to address new problems or
			concerns.</p>
		
		<p>Each version is given a distinguishing version number. If the
			Program specifies a version number of this License which
			applies to it and "any later version", you have the option of
			following the terms and conditions either of that version or of
			any later version published by the Free Software Foundation.
			If the Program does not specify a version number of this
			License, you may choose any version ever published by the Free
			Software Foundation.</p>
		
		<p>10. If you wish to incorporate parts of the Program into other
			free programs whose distribution conditions are different,
			write to the author to ask for permission. For software which is
			copyrighted by the Free Software Foundation, write to the Free
			Software Foundation; we sometimes make exceptions for this.
			Our decision will be guided by the two goals of preserving the
			free status of all derivatives of our free software and of
			promoting the sharing and reuse of software generally.</p>
		
		<h2>NO WARRANTY</h2>
		
		<p>11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
			WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
			APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
			COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
			"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
			IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
			WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
			PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF
			THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
			YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
			CORRECTION.</p>
		
		<p>12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
			WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
			MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
			LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
			INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
			INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS
			OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED
			BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
			WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
			BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.</p>
		
		<p>END OF TERMS AND CONDITIONS</p>
		
		<h2>How to Apply These Terms to Your New Programs</h2>
		
		<p>If you develop a new program, and you want it to be of the greatest
			possible use to the public, the best way to achieve this is to
			make it free software which everyone can redistribute and
			change under these terms.</p>
		
		<p>To do so, attach the following notices to the program. It is
			safest to attach them to the start of each source file to most
			effectively convey the exclusion of warranty; and each file
			should have at least the "copyright" line and a pointer to where
			the full notice is found.</p>
		
		<p><code>&lt;one line to give the program's name and a brief idea of
			what it does.&gt; Copyright (C) &lt;year&gt;
			&lt;name of author&gt;</code></p>
		
		<p><code>This program is free software; you can redistribute it
			and/or modify it under the terms of the GNU General Public
			License as published by the Free Software Foundation; either
			version 2 of the License, or (at your option) any later
			version.</code></p>
		
		<p><code>This program is distributed in the hope that it will be
			useful, but WITHOUT ANY WARRANTY; without even the implied
			warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR
			PURPOSE. See the GNU General Public License for more
			details.</code></p>
		
		<p><code>You should have received a copy of the GNU General Public
			License along with this program; if not, write to the Free
			Software Foundation, Inc., 51 Franklin St, Fifth Floor,
			Boston, MA 02110-1301 USA</code></p>
		
		<p>Also add information on how to contact you by electronic and
			paper mail.</p>
		
		<p>If the program is interactive, make it output a short notice like
			this when it starts in an interactive mode:</p>
		
		<p><code>Gnomovision version 69, Copyright (C) year name of
			author Gnomovision comes with ABSOLUTELY NO WARRANTY; for
			details type `show w'. This is free software, and you are
			welcome to redistribute it under certain conditions; type
			`show c' for details.</code></p>
		
		<p>The hypothetical commands `show w' and `show c' should show the
			appropriate parts of the General Public License. Of course,
			the commands you use may be called something other than `show w'
			and `show c'; they could even be mouse-clicks or menu
			items--whatever suits your program.</p>
		
		<p>You should also get your employer (if you work as a programmer) or
			your school, if any, to sign a "copyright disclaimer" for the
			program, if necessary. Here is a sample; alter the names:</p>
		
		<p><code>Yoyodyne, Inc., hereby disclaims all copyright
			interest in the program `Gnomovision' (which makes passes at
			compilers) written by James Hacker.</code> </p>
		
		<p><code>&lt;signature of Ty Coon&gt;, 1 April 1989 Ty Coon,
			President of Vice</code></p>
		
		<p>This General Public License does not permit incorporating your
			program into proprietary programs. If your program is a
			subroutine library, you may consider it more useful to permit
			linking proprietary applications with the library. If this is
			what you want to do, use the GNU Library General Public License
			instead of this License.</p>
